Abstract

The invention discloses a washing machine control method and device based on turbidity and conductivity detection. The method includes the steps of controlling a washing machine to get in the calibration stage, and obtaining a turbidity calibration value, a turbidity judgment reference value, a conductivity calibration value, a conductivity judgment reference value and a temperature calibration value of water in a washing drum; controlling the washing machine to get in the prewashing stage, obtaining a first turbidity value of the water after washing is carried out for prewashing time, and judging the put amount of washing agents, the main washing water inlet amount and the main washing time according to the first turbidity value, the turbidity calibration value and the turbidity judgment reference value; controlling the washing machine to get in the main washing stage; controlling the washing machine to get in the rinsing stage, and obtaining the first conductivity and a first temperature value; calculating a first result according to the first conductivity, the conductivity calibration value, the conductivity judgment reference value, the temperature calibration value and the first temperature value, and determining whether the washing machine gets in the spin-dry stage or not according to the first result; controlling the washing machine to get in the spin-dry stage, and finishing washing.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a washing machine control method and device based on turbidity and conductivity detection. Background technique [0002] With the continuous improvement of living conditions, the user's demand for washing machine functions also increases. Due to the different degrees of dirt on the clothes, the detergent, water and time required for washing them should also be different. Therefore, some washing machines have been equipped with a device for automatically injecting detergent, which can calculate the required amount of detergent based on the weight of the clothes, etc., and automatically inject. [0003] However, due to factors such as the type of detergent, the amount of detergent used, the washing temperature, and water quality, although the clothes after washing have been cleaned, there may be a small amount of detergent residue, which will cause damage to the user'...
